As interest in vocational competency development projects increases, support is increasing. In this study, in order to study ways to improve participation in vocational competency development training, related factors are selected and the main factors influencing them are derived. The main factors were influencing factors were identified and ways to improve participation rate of vocational competency development were studied. Variables were selected through prior research, and data were collected and analyzed through in-depth group interviews. Based on factor analysis and reliability analysis, as a result of confirming the factors that influence the plan for improving participation in vocational competency development training by applying the backward stage selection (condition) method of logistic regression analysis, the case of respect for minorities in the 7-point Likert scale The closer to 7 was, the higher the probability of being classified as having never participated, and the other factors except minority respect, Likert scale closer to 7 indicates higher probability of bening classified as having never participated, except for the minority respect factor. Therefore, it was confirmed that lowering the scale of the factor of respect for minority, which is job satisfaction, and increasing the factors of individual characteristics such as annual salary and organizational commitment, training system for job satisfaction, and quality assurance have effects on improving participation rates in vocational competency development training.

Previous work has shown that men both explain and value the act of explaining more than women, as explaining conveys expertise. However, previous studies are limited to English. We conducted an exploratory study to see if similar patterns are seen amongst Japanese speakers. We examined three registers of Japanese: conversational interviews, simulated speeches, and academic presentations. For each text, we calculated two measures: lexical density and the percentage of the text written in kanji. Both are indicators of expository language. Men produced significantly higher scores for the interviews and speeches. However, the results for the presentations depend on age and academic field. In fields in which women are the minority, women produce higher scores. In the field in which men are the minority, younger men produced higher scores but older men produced lower scores than women of the same age. Our results show that in academic contexts, the explainers are not necessarily men but rather the gender minority. We argue that such speakers are under social pressure to present themselves as experts. These results show that the generalization that men tend to explain more than women does not always hold true, and we urge more academic work on expository language.

The electronic and magnetic properties for Mn-adsorbed on the chalcopyrite (CH) AlGaP2 semiconductor are investigated by using first-principles FPLMTO method. The clean CH-AlGaP2 without adsorbed Mn is a p-type semiconductor with a direct band-gap. The Mn-adsorbed CH-AlGaP2 exhibits the ferromagnetic state. It is more energetically stable than the other magnetic ones. The interstitial site on P-terminated surface is more energetically favorable one than the Al/Ga-terminated surface, or the other adsorbing sites. In the case of Mn-adsorbed Al/Ga-terminated surface, it is induced a strong coupling between Mn-3d and neighboring P-3p electrons. The holes of partially unoccupied minority Mn-3d state and majority (or minority) Al-3p or P-3p state are induced. Thus a high magnetic moment of Mn is sustained by holes-mediated double-exchange coupling. It is noticeable that the semiconducting and half-metallic characteristics of CH-AlGaP2:Mn thin film is disappeared.

This paper reviewed the past social discussion and health research results on sexual minorities to suggest a future direction. Studies have been done to increase the social inclusion of sexual minorities and promote the health of sexual minorities. However, there is still a lot of exclusive awareness of sexual minorities in Korean society, and the researchers have not identified their health status. Studies have shown that factors that hinder lesbian, gay, bisexual, transgender, and intersex (LGBTI) people from accessing medical services are the lack of knowledge and awareness of LGBTI people and attitudes not inclusive of LGBTI people's culture. Thus, it is necessary to identify the health status of each sexual minority type and prepare health promotion measures accordingly in national health research. In addition, it is essential to provide medical personnel with sexual minority education and introduce a sexual minority education curriculum that includes theory and practice into the health care curriculum. The result of this paper may be able to act as a guide for future operation plans in health research on sexual minorities.

Many researchers are trying hard to minimize the incidence of cancers, mainly Gastric Cancer (GC). For GC, the five-year survival rate is generally 5-25%, but for Early Gastric Cancer (EGC), it is almost 90%. Predicting the onset of stomach cancer based on risk factors will allow for an early diagnosis and more effective treatment. Although there are several models for predicting stomach cancer, most of these models are based on unbalanced datasets, which favours the majority class. However, it is imperative to correctly identify cancer patients who are in the minority class. This research aims to apply three class-balancing approaches to the NHS dataset before developing supervised learning strategies: Oversampling (Synthetic Minority Oversampling Technique or SMOTE), Undersampling (SpreadSubsample), and Hybrid System (SMOTE + SpreadSubsample). This study uses Naive Bayes, Bayesian Network, Random Forest, and Decision Tree (C4.5) methods. We measured these classifiers' efficacy using their Receiver Operating Characteristics (ROC) curves, sensitivity, and specificity. The validation data was used to test several ways of balancing the classifiers. The final prediction model was built on the one that did the best overall.

Purpose: Controlling and minority shareholders sometimes have conflicting interests. Controlling shareholders who do not have adequate monitoring can exhibit a strong tendency to maximize their personal wealth. In this case, cash holdings can be the easiest means for them to pursue their personal interests. This study examined whether the largest shareholder's ownership proportion affected the speed at which firms adjust their cash holdings to target levels in Korean distribution and service companies. Research design, data, and methodology: The study uses regression analysis to examine 834 firm-year samples listed on the KOSPI between 2013 and 2018 in the distribution and service sectors. Results: The largest shareholder's ownership is positively related to a firm's cash holdings adjustment speed. That is, the larger the largest shareholder's ownership, the faster the firm adjusts its cash holdings to achieve the target level. Conclusions: This study contributes to the literature by providing evidence that the cash holdings adjustment speed in Korean service and distribution companies is affected by the largest shareholder's ownership. As the agency problem between controlling and minority shareholders in Korea is a major issue, minority owners' sensitivity to agency costs may help restrict controlling owners' ability to maximize their personal wealth.

This study aims to illustrate the essence of meaning through sexual minorities' participant experiences in a sexual minority community. This research intends to explore essential meaning structure revealed in sexual minorities' reasons for joining a sexual minority community and in their experience in community activities. The study participants were 8 sexual minorities, and data was collected by in-depth interview. Data analysis was described using Giorgi's analysis methodology in phenomenological research method. As a result, the sexual minorities' participation was consisted of 13 meaning units, 6 derived topics, and 3 essential topics, which were 'An unquenchable thirst', 'Another world called oasis', and 'Real estrangement' Moreover, based on the essential topics, the study participants' common meaning of essence was analyzed as 'spiritual diaspora'. Sexual minority communities shall contribute to developments of own organizations through mutual compensations by vitalizing exchanges with other communities based on this study. Also, the communities should the variety in sexual minorities to allow various people's participation. People's awareness on sexual minorities must be transformed so that closed communities can change. Comprehensive knowledge on sexual minorities should be distributed in the social welfare fields so that sexual minorities may search solutions on issues through various access not limited to certain communities.

As the "Partial Amendment to the Vocational Competency Development Act" was passed, and the mandatory refresher training was legislated in March 2020, HRD education institutions has prepared a plan for the improved refresher training to strengthen the competency of vocational training teachers and to improve the quality of refresher training. However, as demand for refresher training is concentrated in partial occupations, it is necessary prepare a separate plan to recognize personal learning as a refresher training for a minority of teachers who are not provided with a training. Therefore, this study aims to identify areas of a minor training occupations that don't exist many participants for a refresher training and to derive ways to recognize their multiple education experiences and participations instead of attending a refresher training. To this end, literature review, analysis of current situation, consultation with stakeholders, and written interviews with experts were conducted. As a result, a minority of training occupations was defined as type 1 and type 2 and ways of the recognition of refresher training for minority of training occupations which embrace various educational types were derived. Lastly, discussions and suggestions on the expansion of the scope of the recognition of refresher training for minority of training occupations were provided.
